The SparkFun Power Delivery Board takes advantage of the power delivery standard with the use of a standalone controller from STMicroelectronics, the STUSB4500.

The SparkFun Qwiic Multiport adds additional ports to boards that have only one Qwiic port on their I2C bus. Once added, you can use it as a hub to add as many I2C devices to the bus as you need [1] ! You can also use the board as an alternative to a daisy chained configuration.
